Want to improve your website’s ranking and get more visitors?
SEO website crawlers can be beneficial! What they are, why they are important, and how to use them to improve your SEO are the main topics of this blog.
After scanning your website, an SEO website crawler looks for on-page and technical SEO issues. Fixing these issues can help your website rank higher and attract more visitors from search engines.
In short, these tools detect basic to more complex website errors so you can correct them and improve your rankings.
Search engines like Google use SEO website crawlers to read and understand websites. But SEO experts can also use them to find problems, discover new opportunities to improve their ranking in search, and even gather insights from competitors.
There are many crawling and scraping tools available online. In this guide, we’ll explain what SEO website crawlers do, how they work, and how to use them safely to improve your website.
What is an SEO Website Crawler?
An SEO website crawler, also called a bot or spider, is a smart tool that scans and studies websites, just like search engines do. These tools show how search engines explore your site and provide useful details about your website’s structure, content, and overall performance.
Crawlers help find problems that might not be obvious but can impact search rankings. They detect issues like broken links, duplicate content, and indexing errors that could affect your website’s visibility.
Why is SEO Website Crawler Important for Website Optimization?
SEO website crawlers are key to improving your website because they:
A. Find Broken Links – They detect links that lead to missing pages, which can hurt both user experience and SEO.
B. Identify Duplicate Content – They spot pages with identical or very similar content, which can confuse search engines and lower your ranking. You can rewrite such content with AI-powered tools like Tarantula to improve SEO.
C. Detect Indexing Problems – They highlight pages that search engines struggle to read, helping ensure all important content is visible and searchable.
What to Consider When Choosing an SEO Website Crawler ?
When picking an SEO website crawler, certain features can help you get better results:
➕ Crawl Depth and Speed
A good tool should scan your entire website, no matter its size, without slowing it down. It should also let you adjust how deep and fast it crawls to avoid overloading your server.
➕ Easy-to-use interface
An intuitive interface makes understanding and acting upon the collected data simpler. Look for tools that present data in an intelligible, actionable way and have dashboards and filtering options that can be customized. With the help of Tarantula, even novices can easily navigate and use it thanks to its user-friendly interface.
➕ Integration Skills
The best crawlers give you a complete picture of how well your website is performing by integrating easily with other crucial tools like Google Analytics and Search Console. This integration makes correlating crawl data with actual user behavior and search performance easier.
➕ Reporting and visualisation features
Good reporting features turn complex data into clear insights. Look for a tool that offers custom reports, visual charts, and different export options. With Tarantula, you can use AI to find hidden SEO opportunities and understand search intent.
